I had the SDS-470 for a few months after I got my D-sonic for my upstairs theater. I've since when to only 3 channels upstairs and my denon 4311 is more than enough and I ended up selling it. It was a great amp, I actually wish I still had it.

I agree. The Sunfire amazes me for how loud you can play it for extended times and it doesn't even get warm. I recently built a containment around my equipment rack on the back side so that the HVAC that is in the adjacent room will not transmit sound into the theater. It worked great but I was thinking that I would need a fan for air flow. So I ran music really loud for about half an hour and the Sunfire was barely warm. Actually my UMC-1 was a little warmer than the Sunfire and it is only a pre-amp, no amp section!

Great amp. I have seen reports on the TGA-5401 (same amp design except with 5 channels) that when driving two channels it can hit 600watts for each @ 4 ohms. I doubt it will hit 800X7 but still very powerful and cool running. I bet it will do pretty well on the 215RT and RM's.

Actually, the 7401 is only 800 watts for front stage channels, the other 4 channels are just 400 watts per 2 channels. It is a little deceptive how the ratings are worded, but that is in fact accurate/.

Not sure where you got your info but if you look at the 7401 specifications on the Sunfire Website, it unambiguously shows all 7 amp channels outputting the same WPC.

No "DWTS" just waiting on pins and needles for my OS...Jeff is bringing it Thursday! I did watch Gravity the other night and wow what a difference the theater experience is with a lower noise floor, especially for a movie like that. I had to tell the wife no popcorn during the quiet scenes.. lol!

YEAYA! 3 OS! €^< in FUN! Sorry I had to say that! And I hope you guys saved some Hawaiian Host Chocolates to munch on first before you guys crank those bad boys up. Oh, and watch out for the nasty, nauseated, puking symptom... Lol!

N8 thanks. I didn't know you are such a genius computer nerd... haha... I am going to check out the sony 500es and if I don't hear much news about 4k blurays in a few months time I might just buy the 55es instead and wait a couple years. Unless of course if the 500es blows me away with 2k content

Quiet night on the forum....everybody watching Dancing with The Stars?

Just a little grocery shopping ya know. Picked up Act of Valor and watched it for the first time. Great movie for sure and some decent impacts with the gun shots in numerous scenes. But the deep bass was entirely non existent! I think my submersives only worked around 50hz up on some of the impactful gun shots and that was it. Okay surround effects with a few in the movie. It is just weird how some movies have amazing effects and others were just mixed and created with minimal. One thing I was thinking about Dgage when you were talking about your quest for chest slamming 100% satisfying mid bass was the source. Really we buy all this stuff but really it's all about the source.
